Since the early 1980’s, computer-aided design software (CAD) has taken over the engineering industry as the standard tool used for drafting and design of mechanical components and assemblies. Immediately, projects were able to go from concept to prototype in record time. A major advantage was the added product design flexibility, which allowed engineers to avoid costly mistakes when changes to the design of one component were not passed along to other affected parts of the assembly. Computer design also brought about the ability to visualize complex technical elements that are difficult to conceive in a two dimensional layout.

While doing the design and engineering of any plant or refinery, accurate 3D modeling is an important requirement. Take a look at this guide that will give you the idea regarding 3D modeling importance.

NIST recently published a report from the Model-Based Enterprise/Technical Data Package summit they hosted last December. You might wonder, why should you care about this subject? I could explain it, but I think the report does a pretty good job. Take some time to read the following, taken from the report. It'll be worth it.
